Use correct KCIDB package_name for debug builds
When running complete pipelines for debug variants, the package_name variable on the KCIDB Build is configured correctly to contain -debug.
When running pipelines that have debug jobs marked with DEBUG_KERNEL via test_debug=true, this was not the case yet. Fix that very carefully only for the KCIDB Build package_name variable.
